Special Issue Information

Dear Colleagues,

The present Special Issue is organized to encourage potential authors to disseminate their recent research achievements related to sustainability in civil engineering such as green building materials, structures, and techniques, while compiling the research results for potential readers of the journal Sustainability. Such topics related to sustainability are in line with policies in many countries to deal with global climate change all over the world. Sustainable buildings or structures can be realized with green materials or efficient structural systems. It involves material saving, sectional optimization, using by-products, recycled materials, and energy-efficient materials such as low thermal conductivity materials for better thermal insulation. Structural performances should also be validated considering the material characteristics when sustainable materials are used for the construction of buildings. Not only for the construction of buildings, but also sustainability related to maintenance such as monitoring, inspection, and strengthening of the existing building structures can be considered to achieve sustainable green buildings.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following: green building material, high-performance construction material, recycled concrete, composite structures, sustainable construction materials, structural reliability, structural strengthening and rehabilitation, structural performance with sustainable material, inspection and maintenance, and non-destructive evaluation of existing structures.

We look forward to receiving your contributions.

Extensive use of cement in the construction industry increases CO2 emissions and has a negative impact on the environment. In this work, recycled coarse aggregate (RCA) from construction and demolition wastes (C&DW) was used to fabricate sustainable pervious concrete (PC). In order to mitigate the environmental hazards of excess cement waste and to improve the engineering properties of PC, silica fume (SF) and ground granulated blast-furnace slag (GGBS) were added. The effects of SF and GGBS on the compressive strength, permeability coefficient, porosity, and abrasion resistance of recycled aggregate pervious concrete (RAPC) were investigated. The results show that the incorporation of GGBS and SF effectively improves the compressive strength of RAPC but reduces the permeability coefficient and porosity. Moreover, due to the filling effect and pozzolanic activity, the incorporation of GGBS and SF significantly enhances the abrasion resistance of RAPC. Furthermore, the relationships between the compressive strength, permeability coefficient, porosity, and abrasion resistance of RAPC are clarified. The optimum replacement is achieved when the SF content is 7%, and the GGBS content is 20%, respectively, which results in the highest compressive strength (28.9 MPa) and the lowest permeability coefficient (1.2 mm/s) at 28 days, and the lowest mass loss rate (12.1%) after the Cantabro abrasion test.

As an environmentally friendly cement material in green buildings, due to its low contribution to air pollution and its substantial use of solid waste, supersulfated cement (SSC) has been extensively studied. However, the low early strength of sustainably utilized SSC needs to be addressed. In order to use SSC to achieve great reductions in energy consumption during industrial production, the effects of triethanolamine (TEA), diethanolisopropanolamine (DEIPA) and triisopropanolamine (TIPA) (with dosages ranging from 0.02% to 0.08%) on the strength and hydration of SSC were studied, and the underlying mechanism was analyzed by TGA, XRD and SEM. The results show that TEA and DEIPA significantly improve the 3-day and 28-day strength of SSC. The former is better at low dosages, while the latter is more suitable for high dosages. TIPA also enhances the 3-day strength of SSC, but it is not as good as the other two alkanolamines. The chelation of alkanolamine with Al3+ ions plays an important role in the strength development of SSC, which accelerates the decomposition of slag and the formation of ettringite. In summary, adding alkanolamines to low-carbon cement systems with a high proportion of industrial by-products such as SSC is a potential and effective solution. In addition, alkanolamines can be used as a strength promoter for most low-carbon blends, which fully utilize solid waste. Full article
